local variable 'filter_id' referenced before assignment
If the interface is accidentally added some tc rules not through
neutron, for example, the interface has two tc rules, the first rule is
"filter protocol all ...", the second rule is "match ...". This first
rule mismatch FILTER_ID_REGEX and the second rule starts with "match",
so the code will execute this statement:
filterids_for_ip.append(filter_id)
But filter_id has not been assignment at this time.
